| FindLibExiv2 | ||
| ------------ | ||
| Try to find the Exiv2 library. | ||
| This will define the following variables: | ||
| ``LibExiv2_FOUND`` | ||
| True if (the requested version of) Exiv2 is available | ||
| ``LibExiv2_VERSION`` | ||
| The version of Exiv2 | ||
| ``LibExiv2_INCLUDE_DIRS`` | ||
| The include dirs of Exiv2 for use with target_include_directories() | ||
| ``LibExiv2_LIBRARIES`` | ||
| The Exiv2 library for use with target_link_libraries(). | ||
| This can be passed to target_link_libraries() instead of | ||
| the ``LibExiv2::LibExiv2`` target | ||
| If ``LibExiv2_FOUND`` is TRUE, it will also define the following imported | ||
| target: | ||
| ``LibExiv2::LibExiv2`` | ||
| The Exiv2 library | ||
| In general we recommend using the imported target, as it is easier to use. | ||
| Bear in mind, however, that if the target is in the link interface of an | ||
| exported library, it must be made available by the package config file. | ||
| Since 5.53.0. | ||
